Genes affected

ARFIP2 (HGNC:17160): (ADP ribosylation factor interacting protein 2) Enables several functions, including GTP-dependent protein binding activity; membrane curvature sensor activity; and phosphatidylinositol-4-phosphate binding activity. Involved in actin cytoskeleton organization. Located in cell cortex; ruffle; and trans-Golgi network membrane. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.512G>A (p.R171H) alteration is located in exon 5 (coding exon 4) of the ARFIP2 gene. This alteration results from a G to A substitution at nucleotide position 512, causing the arginine (R) at amino acid position 171 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
